The author himself later added this story to his list of 12 favourite Sherlock Holmes stories.

Watson rents a house in the Surrey town of Reigate so that Holmes, exhausted by his previous investigation, can relax in a rural idyll. A burglary occurs in one of the neighbouring houses, during which unrelated but not valuable items are stolen. A coachman, William Kiruon, is also murdered, and a piece of a note is found in his hand. From the fragment of the note, the detective concludes that it was written by two men who are related to each other, but one of them is younger and the other is older. Also, the time indicated in the note coincides with the time of the coachman's murder.
